Animations of Chemical Principles

These pages provide links
to web pages that illustrate chemical principles, mostly by animating molecules
and atoms. We have assembled the links, and in some cases organized
them together with questions, as noted. Please let us know if any of these
links are broken, but make sure you contact the correct author/webmaster
if there is a problem with the animations, themselves.
We have tried to indicate
the technological requirements (operating systems and special software)
for the animations on each page. We have checked these out with InternetExplorer
5.0.

SimChemistryfor
Windows - Live molecular dynamics simulations for
chemistry teaching and experimentation. Provides tutorials on several
subjects and an interactive simulation of a simple reaction. It is programmable,
and we hope to provide new simulations in the future. Free for 30
days of use; then costs 50 pounds sterling.

- pressure versus altitude in the absence of turbulent mixing. Although
the results suggest that the concentration of heavy atoms/moelculesfall
off faster with altitude than does the concetration of light atoms/molecules,the
real atmosphere is well mixed; it behaves like a gas with molar mass28.8

Not animations, but "a visual environment to solve problems, pursue what-ifscenarios,
perform numerical experiments, and have fun learning thermodynamics!"
